Rete anomaly of the middle cerebral artery: case series of 13 patients from the Northeastern United States.

Background: Rete middle cerebral artery (MCA) is a rare anomaly of the intracranial circulation that mimics congenital Moyamoya disease (MMD). Similar to MMD, it is reported almost exclusively in East-Asian ethnicities. Here, we report 13 patients with rete MCA anomaly from a predominantly non-Asian background in the USA.

Digital wear analysis and retention of poly-ether-ether-ketone retentive inserts versus conventional nylon inserts in locator retained mandibular overdentures: in-vitro study.

Objective: this study aimed to digitally compare wear behavior and retention between PEEK and nylon retentive inserts used in locator-retained, mandibular implant overdentures when attachment design and size were standardized.

Materials And Methods: A total of sixty-four inserts (32 PEEK and 32 nylon inserts); were picked-up in implant overdentures. Overdentures of both groups were submerged in artificial saliva and mounted to chewing simulator.

Facilitating glaucoma diagnosis with intereye neuroretinal rim asymmetry analysis using spectral-domain optical coherence tomography.

Purpose: To determine whether intereye asymmetry of a three-dimensional neuroretinal rim parameter, the minimum distance band, is useful in differentiating normal eyes from those with open-angle glaucoma.

Materials And Methods: This is a cross-sectional study of 28 normal subjects and 33 glaucoma subjects. Subjects underwent spectral domain optical coherence tomography imaging of both eyes.

A Machine Learning Model to Predict Citation Counts of Scientific Papers in Otology Field.

One of the most widely used measures of scientific impact is the number of citations. However, due to its heavy-tailed distribution, citations are fundamentally difficult to predict but can be improved. This study was aimed at investigating the factors and parts influencing the citation number of a scientific paper in the otology field.

Pediatric intraocular pressure measurements: Tonometers, central corneal thickness, and anesthesia.

Measuring intraocular pressure (IOP) is the cornerstone of a comprehensive glaucoma examination. In babies or small children, however, IOP measurements are problematic, cannot often be performed at the slit lamp, and sometimes require general anesthesia. Therefore, it is essential for an ophthalmologist who examines a pediatric patient to be aware of the different tonometers used in children, as well as the effects of central corneal thickness and anesthesia on IOP measurements.

Study of platelet activation, hypercoagulable state, and the association with pulmonary hypertension in children with β-thalassemia.

Background: The increased survival rate of thalassemic patients has led to unmasking of management related complications which were infrequently encountered.

Objective: Study the increased coagulation and platelet activation in children with β-thalassemia, to analyze the factors that lead to such hypercoagulable state and to study pulmonary hypertension (PH) in conjunction with platelet activation and hypercoagulable state in children with β-thalassemia.

Methods: 36 Egyptian children with β-thalassemia with a mean age of 9.

Deformity correction with an external fixator: ease of use and accuracy?

The Taylor spatial frame (Smith & Nephew, Memphis, Tennessee) is a hexapod frame that differs from the well-known Ilizarov fixator in that it works in conjunction with special software programs and can simultaneously correct 6 axes of deformity. The aim of this study was to evaluate the ease of use and accuracy of the Taylor spatial frame. We used the Taylor spatial frame with the older software, Version 2, and the newer Internet-based program, Version 3.

Hyperhomocysteinemia is A risk marker for development of maternal pre-eclampsia.

The objective of the current study was to determine whether homocysteine elevations precede the development of pre-eclampsia, and to examine the relationship between the occurrence of pre-eclampsia and the degree of hyperhomocysteinemia, so as to find a new prognostic parameter for women with liable to develop pre-eclampsia. The study comprised 103 pregnant females chosen of those attending the Antenatal Care Unit at Benha University Hospital and accepted to donate blood samples at the 16th week of gestation. Women, who delivered at Benha University Hospital, were retrospectively allocated into two groups: Control group (Group C): comprised 64 (71.
